11 Safety Precautions Warning Warning Cautions Correctly make the settings because the DirectPowerControl function block directly output the manipulated variable without feeding back. Not doing so may result in serious accident or fire due to overheating. Monitor overheating and build an application to safely stop the devices if overheating occurs. Correctly make the settings because the DirectPowerControl function block directly output the manipulated variable without feeding back. Not doing so may result in serious accident, steam explosion, or frostbite due to overcooling. Monitor overcooling and build an application to safely stop the devices if overcooling occurs. Caution Read all related manuals carefully before you use this library. Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits. Check the user program, data, and parameter settings for proper execution before you use them for actual operation. The Sysmac Library and manuals are assumed to be used by personnel that is given in Intended Audience in this manual. Otherwise, do not use them. Perform the test run by holding an emergency stop switch in hand or otherwise prepare for rapid motor operation in an application to control the motor. Also perform the test run by using the parameters for which the motor does not rapidly accelerate or decelerate before you gradually adjust the parameters. In an application of heating or cooling, perform the test run by using the parameters for which rapid temperature changes will not occur before you gradually adjust the parameters. You must confirm that the user program and parameter values are appropriate to the specifications and operation methods of the devices. The sample programming shows only the portion of a program that uses the function or function block from the library. When using actual devices, also program safety circuits, device interlocks, I/O with other devices, and other control procedures. Understand the contents of sample programming before you use the sample programming and create the user program. Sysmac Library User s Manual for Temperature Control Library (W551) 9

12 Precautions for Correct Use Precautions for Correct Use Using the Library When you use the library, functions or function blocks that are not described in the library manual may be displayed on the Sysmac Studio. Do not use functions or function blocks that are not described in the manual. You cannot change the source code of the functions or function blocks that are provided in the Sysmac Library. The multi-execution (buffer mode) cannot be performed in the Sysmac Library. Provide safety measures such as monitoring overheating or overcooling, and other measures outside the functions or function blocks when you use the Temperature Control Library. Using Sample Programming Create a user program that will produce the intended device operation. Check the user program for proper execution before you use it for actual operation. Operation Specify the input parameter values within the valid range. In the function or function block with an Enabled output variable, if the value of Enabled is, do not use the processing result of the function or function block as a command value to the control target. In the function block with Execute, do not perform re-execution by the same instance. The output value of the function block will return to the default value. 10 Sysmac Library User s Manual for Temperature Control Library (W551)

26 Common Variables Common Variables This section describes the specifications of variables (EN, Execute, Enable, Abort, ENO, Done, CalcRslt, Enabled, Busy, CommandAborted, Error, ErrorID, and ErrorIDEx) that are used for more than one function or function block. The specifications are described separately for functions, for execute-type function blocks, and for enable-type function blocks. Definition of Input Variables and Output Variables Common input variables and output variables used in functions and function blocks are as follows. Variable I/O Data type Function/function block type to use Function block Executetype Enabletype Function Meaning Definition EN Input BOOL OK Execute The processing is executed while the variable is. Execute OK Execute The processing is executed when the variable changes to. Enable OK Run The processing is executed while the variable is. Abort BOOL OK Abort The processing is aborted. You can select the aborting method. 24 Sysmac Library User s Manual for Temperature Control Library (W551)

27 Common Variables Variable ENO Output BOOL OK Done The variable changes to when the processing ends normally. It is when the processing ends in an error, the processing is in progress, or the execution condition is not met. Done BOOL OK Done The variable changes to when the processing ends normally. It is when the processing ends in an error, the processing is in progress, or the execution condition is not met. Busy BOOL OK OK Executing The variable is when the processing is in progress. It is when the processing is not in progress. CalcRslt LREAL OK Calculation The calculation result is output. Result Enabled BOOL OK Enabled The variable is when the output is enabled. It is used to calculate the control amount for motion control, temperature control, etc. Command Aborted I/O Data type Function/function block type to use Function block Executetype Enabletype Function Meaning BOOL OK Command Aborted Definition The variable changes to when the processing is aborted. It changes to when the processing is re-executed the next time. Error BOOL OK OK Error This variable is while there is an error. It is when the processing ends normally, the processing is in progress, or the execution condition is not met. ErrorID WORD OK OK Error Code An error code is output. ErrorIDEx DWORD OK OK Expansion Error Code An expansion error code is output. Execute-type Function Blocks Processing starts when Execute changes to. When Execute changes to, Busy also changes to. When processing is completed normally, Busy changes to and Done changes to. When continously executes the function blocks of the same instance, change the next Execute to for at least one task period after Done changes to in the previous execution. If the function block has a CommandAborted (Instruction Aborted) output variable and processing is aborted, CommandAborted changes to and Busy changes to. If an error occurs in the function block, Error changes to and Busy changes to. For function blocks that output the result of calculation for motion control and temperature control, you can use the BOOL input variable Abort to abort the processing of a function block. When Abort changes to, CommandAborted changes to and the execution of the function block is aborted. Sysmac Library User s Manual for Temperature Control Library (W551) 25

28 Common Variables In-out variables Input variables InOut_Val Execute Abcd_instance Abcd InOut_Val Done Busy CommandAborted Error ErrorID ErrorIDEx In-out variables Output variables If Execute is and Done, CommandAborted, or Error changes to, Done, Command- Aborted, and Error changes to when Execute is changed to. If Execute is and Done, CommandAborted, or Error changes to, Done,Command- Aborted, and Error changes to for only one task period. If an error occurs, the relevant error code and expansion error code are set in ErrorID (Error Code) and ErrorIDEx (Expansion Error Code). The error codes are retained even after Error changes to, but ErrorID is set to 16#0000 and ErrorIDEx is set to 16# when Execute changes to. Timing Charts This section provides timing charts for a normal end, aborted execution, and errors.

30 Common Variables Enable-type Function Blocks Processing is executed while Enable is. When Enable changes to, Busy also changes to. Enabled is during calculation of the output value. If an error occurs in the function block, Error changes to and Busy and Enabled change to. When Enable changes to, Enabled, Busy, and Error change to. In-out variables Input variables InOut_Val Enable Abcd_instance Abcd InOut_Val Enabled CalcRslt Busy Error ErrorID ErrorIDEx In-out variables Output variables If an error occurs, the relevant error code and expansion error code are set in ErrorID (Error Code) and ErrorIDEx (Expansion Error Code). The error codes are retained even after Error changes to, but ErrorID is set to 16#0000 and ErrorIDEx is set to 16# when Enable changes to. For function blocks that calculate the control amount for motion control, temperature control, etc., Enabled is when the value of CalcRslt (Calculation Result) is incorrect. In such a case, do not use CalcRslt. In addition, after the function block ends normally or after an error occurs, the value of CalcRslt is retained until Enable changes to. The control amount will be calculated based on the retained CalcRslt value, if it is the same instance of the function block that changed Enable to. If it is a different instance of the function block, the control amount will be calculated based on the initial value. Timing Charts This section provides timing charts for a normal end and errors.

The values output by the function block returns to the initial values. Specify the values of the input parameters within the valid ranges. Additional Information The execution period of the PID control instruction depends on the sampling period of the PID control instruction. Therefore, the task period of the NJ/NX/NY-series Controller and the execution period of the PID control instruction are not synchronized. It is therefore possible that the MV from this function block will not be detected by the PID control instruction when changing from direct MV control to PID control, depending on the value of PIDSwitchingTime. To ensure that the MV from this function block is detected by the PID control instruction, set PIDSwitching- Time as follows: PIDSwitchingTime > PID control instruction sampling period + Task period of task in which this function block is executed Sysmac Library User s Manual for Temperature Control Library (W551) 33

52 TempUniformityFilter Meanings of Variables The meanings of the variables that are used in this function block are described below. Enable This is the execution condition for the function block. Temperature uniformity control processing is performed while the value is. If the value changes to, processing is stopped and the input SP is output to CorrectSP (Corrected SP). RefPointIndex (Reference Point Index) Set a value to determine RefPoint (Reference Point). RefPoint (Reference Point) is a deviation (i.e., the difference between the SP and PV) in the loop that is used as a reference for temperature uniformity. RefPoint (Reference Point) is determined by the value of RefPointIndex (Reference Point Index) as shown in the following table. RefPointIndex = 0 Value RefPointIndex = N (1 to 9) Resulting RefPoint (Reference Point) RefPoint (Reference Point) is the average deviation of all loops for which the corresponding element in FilterEnable is. RefPoint (Reference Point) is the Nth largest deviation of all of the enabled loops. Examples: If RefPointIndex is set to 1, RefPoint (Reference Point) is the highest deviation of all the loops. If RefPointIndex is set to 4, RefPoint (Reference Point) is the fourth highest deviation of all the loops. 50 Sysmac Library User s Manual for Temperature Control Library (W551)

Time T Time Additional Information Normally set RefPointIndex (Reference Point Index) to 0. If temperature uniformity control is being performed for loops with rapid temperature changes and slow temperature changes, set RefPointIndex (Reference Point Index) to a loop with slow temperature changes. The speed of temperature changes of loops is indicated by the time constant of the PV when the SP is changed. Sysmac Library User s Manual for Temperature Control Library (W551) 51

MV [%] Time [sec] If the MVs (manipulated variables) become saturated during a transitional state when the temperature is rising or falling, perform the following adjustments. When the temperature is rising, set RefPointIndex (Reference Point Index) to the loop with the largest deviation (i.e., the lowest temperature). For cooling control, set RefPointIndex to the loop with the smallest deviation (i.e., the highest temperature). Set the SP in a ramp to achieve smooth temperature changes Time [sec] SP Input the set point. If the control target is a heater, input the target temperature. PV Input the process value.

Suitable Value for FilterGain Temperature RP temperature Loop PV Excessively Small Value for FilterGain Time Temperature RP temperature Loop PV Excessively Large Value for FilterGain Time Temperature RP temperature Loop PV FilterEnable Specify the loops for which to perform temperature uniformity control. To enable temperature uniformity control for a loop, change FilterEnable[i] to, where i is the array element number for the loop. To disable temperature uniformity control for a loop, change FilterEnable[i] to. For example, to enable using this function block for four separate heaters, set FilterEnable[1] to FilterEnable[4] to and set FilterEnable[5] to FilterEnable[9] to If FilterEnable changes to for a loop, the SP input to the function block is output as is to CorrectSP (Corrected SP).

56 TempUniformityFilter CorrectSP (Corrected SP) This section describes the processing performed for CorrectSP (Corrected SP). The value of CorrectSP (Corrected SP) is calculated for loops for which FilterEnable is based on the SP, PV, FilterGain, and RefPoint (Reference Point) for each loop. RefPoint is determined inside the function block according to RefPointIndex (Reference Point Index). A processing example for CorrectSP (Corrected SP) when this function block is used for four-loop heater temperature control is provided below. Here, we assume that the heater temperatures are set as shown in the following table before the function block is executed. Heater SP PV Heater Heater Heater Heater Heater 1 SP[1]=100[ C] PV[1]=98.0[ C] Heater 2 SP[2]=100[ C] PV[2]=96.0[ C] Heater 3 SP[3]=100[ C] PV[3]=92.0[ C] Heater 4 SP[4]=100[ C] PV[4]=90.0[ C] Performing Temperature Uniformity Control for the Average of the Heater PVs (PV[1] to PV[4]) The following settings are made. (a) RefPointIndex = 0 (b) FilterGain[1] to FilterGain[4] = 100 [%] (c) FilterEnable[1] to FilterEnable[4] = Process 1: Calculating RefPoint (Reference Point) RefPointIndex is set to 0 (average deviation), so the result of the following formula is calculated as 6.0 [ C]. 4 RefPoint = i=1 (SP[i]-PV[i]) 4 Process 2: Calculating CorrectSP After the reference point is determined, the values of CorrectSP (Corrected SP) are calculated with the following formula. CorrectSP[i] = {(SP[i] - PV[i] - RefPoint) * FilterGain} + SP[i] i : Array element number for loop The following results are calculated and output from the function block: CorrectSP[1] = 96.0 [ C], CorrectSP[2] = 98.0 [ C], CorrectSP[3] = [ C], and CorrectSP[4] = [ C]. 54 Sysmac Library User s Manual for Temperature Control Library (W551)

57 TempUniformityFilter Adjusting to the PV of the Heater with the Nth Largest Deviation The following example shows the processing for temperature uniformity control when the PV with the largest deviation is used as the reference point. a) RefPointIndex = 1 b) FilterGain[1] to FilterGain[4] = 100 [%] c) FilterEnable[1] to FilterEnable[4] = Process 1: Calculating RefPoint If RefPointIndex is set to 1 (largest deviation), the deviations of all loops are calculated, and the deviation of the loop with the largest deviation (10.0 [ C]) is used for RefPoint (Reference Point). a) Loop 1 deviation: 2.0 [ C] (SP[1] - PV[1]) b) Loop 2 deviation: 4.0 [ C] (SP[2] - PV[2]) c) Loop 3 deviation: 8.0 [ C] (SP[3] - PV[3]) d) Loop 4 deviation: 10.0 [ C] (SP[4] - PV[4]) Process 2: Calculating CorrectSP After the reference point is determined, the same formula is used to calculate CorrectSP as in Process 2: Calculating CorrectSP on page 54 of Performing Temperature Uniformity Control for the Average of the Heater PVs (PV[1] to PV[4]) on page 54. The following results are calculated and output from the function block: CorrectSP[1] = 92.0 [ C], CorrectSP[2] = 94.0 [ C], CorrectSP[3] = 98.0 [ C], and CorrectSP[4] = [ C].
